Van Helsing vs Skeletons

Van Helsing is against the harmful skeletons who come back from their graves to haunt the people in this town! Help him shoot them all, so the people can sleep peacefully at night. Sometimes you can't shoot directly at the skeletons. In that case you need to find an object to shoot at, which will fall onto the skeleton and smash him, or you should shoot at the obstacle and remove it to shoot at the skeleton. Good luck!
